Synchronization Using Bit Stuffing

To write a C program to perform the  BIT STUFFING using linux enviroinment.

  Step1: Start the program.
  Step2: Get the messages and check the message for five repeated “1” value.
  Step3: If it is true then add “0” as next value.
  Step4: Print the sending messages one by one.
  Step5: Stop the program.

#include<stdio.h>
#include<string.h>
main()
{
char b[30]={0,0},c[30]={0,0},a[40]="01111110",e[40]="01111110";
int i,j=0,cnt=0,n;
printf("enter the string");
scanf("%s",b);
n=strlen(b);
for(i=0;i<n;i++)
{
c[j]=b[i];
if(b[i]='1')
cnt++;
else
cnt=0;
if(cnt==5)
{
c[++j]='0';
cnt=0;
}
j++;	
}
printf("after bit stuffing \n");
strcat(a,c);
strcat(a,e);
printf("%s",a);
}

Output

[t03it    @localhostt03it   ]$ cc bitstuff.c

[t03it    @localhostt03it   ]$./a.out

enter the string 111111

after bit stuffing

01111110111110101111110
